Process Information : Coal Fired Burner Quarls
Changes in the power industry has led to increasing periods between boiler outages which in turn has put heavier demands on the burner quarl refractories to achieve longer service life
In addition, low NOx burner systems demand accurate throat and profile geometry to ensure the consistent air volume required in controlled under combustion
Process temperatures up to 1400°c
Neutral atmospheres overall but with local reduction and oxidation
Deposition of siliceous slag
Localised abrasion
Rapid delta T in hot start situations
